Minerals Products (Barytes/Barites)
Barytes is the main industrial source of barium. The barytes is usually used as an industrial mineral. It is relatively common and widely distributed, although the bulk of world production is supplied by India. It is known as barytes in Britain, but as barite in most other countries. The name barytes is also given to the commercially traded mineral. However, AHM offer barite ore (lumps) and mesh (generally 200 mesh) API 13A barite for drilling purposes.
Composition and mineralogy
Barytes (synonyms barite: baryte) is a naturally occurring Barium Sulphate mineral (BaSO4 in the proportion 66% BaO and 34%). Barytes can sometimes contain strontium, and forms a complete solid solution series to the mineral celestite (SrSO4).
Barytes Deposits at Mangampet, in Andhra Pradesh
The largest single deposit is the Mangampet deposit in Andhra Pradesh, India where two stratiform lenses up to 1.2 km long and 20 m thick contain over 74 million tonnes of barytes. Annual production from the district is 700 000 tonnes and it contributes about 90% of barytes production in the state. Our Pulverizing mill is situated near to this Barites mining area at Mangampet.
AHM exporters of Barium Sulfate (BaSO4) APi 4.10 and 4.20 as a main product furnishes at Pulverizing unit at Mangampeta, Kodur, A.P State, India that is just <2 miles distance from Barites mine and consequently, it facilities us easy access to the Highways to delivering the cargo promptly at economical cost without compromising on quality.
Extraction and processing
Mining methods vary with the type of deposit. Major stratiform deposits are worked by open pit where this is practicable. The ore is drilled and blasted and then trucked to the mill for processing. Conventional underground methods are used as appropriate to the shape and attitude of the deposit. Vein deposits are worked by shafts and adits, as well as by shallow open-pits. Residual deposits are mainly worked by hand, due to the variable and irregular nature of the mineralization.
Following initial crushing, some barytes is sold as ‘direct shipping ore’, if it is sufficiently pure, to be processed. If there are contaminants, such as waste rock or other minerals such as dolomite, black ash, clay. These may be separated from the barytes by gravity separation, wet grinding and froth flotation. The barytes is then either dried and sold as a powder or processed further for applications.
The main use of barytes accounting >85% production is as a weighting agent in oil and gas well drilling fluids or ‘mud’. Finely ground barytes is added to the drilling fluid (mainly water, but with other chemicals to enhance its performance) to increase the density of the column of fluid above the drill bit and thus assist in preventing a ‘blowout’‡. Barytes can form up to 40% of the fluid by weight. Although there are alternatives, barytes is the favoured weighting agent as it is non-corrosive, non-abrasive, insoluble and non-toxic. The normal specifications are provided by the American Petroleum Institute ('API'). Barytes' particular qualities of high density, low solubility, high brightness and whiteness, chemical inertness, softness and relative cheapness.
Historical price (nominal) variation of barytes. Drilling grade is based on the price for barytes. Usually Demand for drilling fluid that initially consumed much of the supply of all grades of barytes. As a weighting agent in drilling fluids, barytes is very difficult to replace. There are several crucial factors that make barytes ideal as an additive for this application.
Other minerals that can substitute for barytes as a weighting agent in drilling fluid are celestite, galena, calcium carbonate, ilmenite and finely powdered iron ore. However, none of these alternatives meet all the criteria for barytes on price, technical performance, environmental and health and safety considerations.
Specialised applications for barytes offer little scope for significantly increased use. In these markets barytes tends to be chosen in preference to other possible minerals because it is low-cost and readily available. The ability of barytes to block X- rays (second only to lead) and the fact that it is the only X-ray-opaque material that is safe to use in the human body that has led to the under development of new applications in medical science.
The apparent increase in barytes production. Over the last ten years there have been considerable changes in the countries that produce significant quantities of barytes since the production increased directly in response to increasing worldwide drilling activity.
